Backfire if fuel mixture related is more likely the result of a lean mixture, not rich - have you checked for a vacuum leak? Dual ignition properly synchronized? A lot of white smoke at the exhaust suggests coolant in the combustion chamber, perhaps a blown head gasket or cracked head or block - check for a wet plug or better yet do a compression test.

The carburetor should be an EE-22, as I recall the EE-2 was specified for the Light Eight Model 900 upgrade kit when converting from updraft to downdraft. 1933 and 1934 Eight and Super Eight used the EE-22. Since the engines are nearly identical I suspect an EE-2 should give acceptable results in place of the EE-22, they are nearly identical. If it needs a rebuild, a kit is available from Daytona Parts, but treat it like GOLD and be especially gentle with fuel inlet, extremely difficult to source a replacement carburetor or casting. Good instructions come with the kit. Best way to adjust the idle mixture is with a vacuum gauge, follow the vacuum line from the intake manifold and you'll find a plug you can remove and replace with a nipple for attaching the gauge up near the power brake selector valve. Adjust each throat to leanest mixture consistent with the maximum vacuum. You might also check the fuel bowl level. Specs have been posted here previously, try a search on EE-22 .

Looks like you're missing the carburetor fuel bowl heat shield. The link rod from the automatic choke is incorrect though it may function ok. The original link rod was reproduced by Classic and Exotic in Michigan. The cast iron carburetor base casting should be painted in wrinkle finish black and the upper castings in semigloss black. Screws and external hardware should be nickel plated.

Sounds like you need a new Sylphon thermostat for your shutters, I believe Bill Hirsch still has them new though inventory has been tightening in recent years, I heard that the manufacturer, Robertshaw, has ceased production. There are also repair services for them or if you're handy self-repair may be possible. I suggest getting a new one and keeping your old core as a "just in case" for the future.

The bronze reproduction throttle gear was repro'd by the Mauck's years back but now deceased; it may be available from Max Merritt. The link rod is simple to make, others have done so based on a photo I supplied years ago and probably still have, next time I'm on my PC I'll look for it and post again.

Your model Packard is an Eight, not a Standard Eight, use of the word Standard as part of the model name was dropped after 1932. I've been driving and maintaining my 1934 1100 for nearly 60 years and am quite familiar with it, send me a PM with your phone # if you want to discuss at length.
